Which photovoltaic sandwich panel manufacturers in China are good? In fact, without specifying a particular enterprise, the prices of photovoltaic sandwich panels from different brands and manufacturers are influenced by a variety of factors. For example, raw material costs, production processes, and brand added value. Some large-scale manufacturers may have more competitive prices due to cost-sharing advantages, while those focusing on high-end customization may have higher prices.
I. Product Quality
Compliance with Relevant Standards
Good photovoltaic sandwich panels need to meet national and industry-related standards. For instance, in terms of fire resistance, they should reach the corresponding fire resistance grade requirements. Some places require a B1-level limited combustibility standard. In terms of electrical insulation performance, they must also meet the specified values to ensure safe use. However, without specific enterprise information, it’s impossible to determine which enterprises’ products excel in this regard. You might as well first learn about the original manufacturer LUSEN.
Durability
The durability of photovoltaic sandwich panels includes the panel’s resistance to aging and weather resistance. High-quality products will not easily fade, deform, or crack during long-term outdoor use. Generally speaking, sandwich panels made with high-quality core materials and outer layers, and treated specially, have better durability.
II. After-sales Service
Installation Guidance
A well-rounded enterprise will provide detailed installation guidance, including how to correctly install photovoltaic sandwich panels to ensure the best power generation efficiency and safety. This may involve guidance for different installation scenarios, such as roof installation and ground installation.
Warranty
Good enterprises usually offer a warranty service for a certain period. The warranty content may cover product quality issues and power generation efficiency guarantees. For example, some enterprises provide a warranty period of 5 to 10 years.
